JSON quasiquatation for Haskell.

This package expose the function aesonQQ that compile time converts json code into a Data.Aeson.Value. aesonQQ got the signature

aesonQQ :: QuasiQuoter

and is used like

myCode = [aesonQQ| {age: 23, name: "Pelle", likes: ["mac","Haskell"] } |]

where it is important that

  • you got no space in [aesonQQ| and
  • no additional code after |].

The quasiquatation can also bind to variables like

myCode = [aesonQQ | {age: <| age |>, name: <| name |>} |]
 where age = 34 :: Integer
       name = "Pelle"

or contain Haskell code like

myCode = [aesonQQ | {age: <| age + 42 :: Integer |>, name: <| map toUpper name |>} |]
 where age = 34 :: Integer
       name = "Pelle"
